Lead(II) thiocyanate is a chemical compound, more precisely a salt, with the chemical formula Pb(SCN)2.
Lead(II) thiocyanate may be made by reacting lead(II) acetate (Pb(CH3COO)2) solved in water with either potassium thiocyanate (KSCN) or ammonium thiocyanate (NH4SCN), thus causing precipitation of solid lead(II) thiocyanate.
Ion reaction:
- Pb2+(aq) + 2SCN-(aq) → Pb(SCN)2(s)
Lead(II) thiocyanate is reasonably soluble at room temperature, thus it may be difficult to identify in a solution with low concentration of lead(II) thiocyanate. Although it has not been confirmed by other sources than the author of this article, experiments show that even if there is no precipitation of lead(II) thiocyanate in the solution, crystals of the salt may form.
